Steadfast Insurance Co. v. Agricultural Insurance Co., 304 P.3d 747

A three-judge Tenth Circuit panel certified an unsettled Oklahoma law question on equitable subrogation.
The dispute is between GRDA's first-level excess insurer Steadfast and second-level excess insurer Agricultural.
GRDA received first-level excess general liability coverage from Steadfast for 1998–2002; Agricultural provided second-level excess coverage in the same period.
Steadfast and GRDA allocated flooding losses to the 1993–1994 Steadfast policy; Agricultural claims this allocation affected its excess coverage for that year.
GRDA/Steadfast agreed to allocate losses and released further claims, which Agricultural argues shifted costs that it should be able to recover from Steadfast via equitable subrogation.
Lower court ruled against Agricultural; on appeal, the Tenth Circuit certified whether a second-level insurer may pursue equitable subrogation against a first-level insurer despite the insured’s release.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether second-level insurer may sue first-level insurer via equitable subrogation despite insured release.	Agricultural asserts release cannot bar subrogation.	Steadfast argues derivative right rule should bar subrogation.	Yes; second-level may sue, but merits not decided.
